Most failures in growing seedlings due to the sowing of seeds in the wrong cooked or ordinary garden soil, which after 2-3 irrigations becomes hard as cement. In dense soil accumulate large amounts of carbon dioxide and the roots suffocate, especially when there is excessive watering on cloudy cold days.

Gardeners are trying to rectify the situation dressings, making a lot of nitrogen fertilizer, the excess nitrogen causes poisoning plants - on the edge of the leaf appears brown rim. In cold soil (below 10 C), the roots absorb phosphorus badly. If phosphate fertilizer made in sufficient quantities, then carry out foliar fertilizing, spraying the plants on the night of 1% solution of superphosphate.When you add sawdust to the soil nitrogen starvation can occur even when making nitrogen fertilizer at 50 g / m : plants have small leaves pale-green, appressed to stem. A week after the introduction of these fertilizers in doses of 15-20 g / m green leaves, stem and deviate from the veins are green.

Plants need for potassium and magnesium

In cloudy weather, low light plants growing need for potassium and magnesium. With a lack of potassium leaves are dark green, the tips of the lower leaves turn black (edge ??burn). Magnesium starvation especially clearly manifested usually on lower leaves of cabbage and cucumber. Veins of them remain green, and yellow space between them, in acute starvation between the veins formed brown spots of dead tissue. The introduction of 20 g / m kalimagnezii eliminate starvation on these, but the damaged leaves will not recover. If there is no kalimagnezii, then make a 15 g / m potassium salt and spray the plants 1-2% solution of magnesium sulphate (at night).

Flow rate of solution of magnesium sulphate for foliar application 1 to 2 l / m .

Supplementary feeding of trace elements

To prevent starvation of micronutrients foliar feeding is carried out with a solution of the following composition (in g / l) zinc sulfate - 2, copper sulfate - 0.5, cobalt sulfate - 0.3, ammonium molybdate - 0.1. Foliar trace elements can be combined with the introduction of magnesium, but with phosphorus fertilizers . This positive effect on plant development.

You can not score pots and boxes of badly rotted manure, as it affects plant growth, the top young leaves turn yellow due to lack of copper and iron. Signs of deficiency disappear in 10-12 days. If you water the plants with a solution of the following composition, in a bucket of water, 1 g of copper and 5 g of ferrous sulfate, penicillin bottle vinegar to 1 m .

The second hazard cause stunted seedlings receiving - gelled plants.

Transplanting

Seedlings are planted after the cessation of frost. A small number of potted plants can be planted earlier, but the cold snap at night they close the banks or paper bag. Plants carefully removed from the package, dipped into the wells of pre-cooked and covered the roots of the earth, watered, and then the surface of the wells do not fall asleep watered land. Bezgorshechnuyu sprouts from the top shelter for 1-2 days burdock leaves or paper, it can quickly take root vegetables and easier to move the transplant. To restore the root system requires a large amount of oxygen young spines grow back.

Plants must pritenyat, as in this case they can not do without watering for 3-4 days.

Treatment of seedling roots

If seedlings are purchased on the market and the roots of bare, before transplanting them to dip into mash. And 3 parts of clay was added 1 part of fresh mullein and diluted with water until thick sour cream. In the prepared mixture was poured into a small amount of dissolved water IAA (poltabletki to 1 liter of mixture), which stimulates root formation . If there is no mullein and IAA, the mash is prepared from the same clay. Roots dipped gently, being careful not to stain the leaves.

Cover such plants should be within 3-4 days. Because the market is usually not hardened seedlings and needs careful maintenance.
